WASHER.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed December 10, 1906- Serial No. 347,145.

'1 '0 all whom it may concern:

Be it known that I, CHARLES G. E'rrn, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Washers, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure l is a plan view; Fig. 2 is a sectional view on the line 22 ofFig. l; and Fig. 3 is a detail perspective view of a portion of thewasher.

This invention relates to new and useful improvements in washers, andparticularly to washers made of malleable iron or otherma-lleable metal.

The object of my invention is to provide this class of washers withellicient locks both for itself and the nut, which locks are simple andadd nothing to the weight of the washer.

Referring to the drawings which illustrate the preferred form of myinvention, the washer comprises a base flange 1 provided with anintegral boss 2, the free end of which constitutes the washer face 3.When the washer is in use a bolt or rod 4 passes through the boss and anut 5 bears against the washer face.

The base flange 1 is provided with one or more notches (3 which may beof any suitable shape. That part of the base flange in which thesenotches are formed is preferably beveled to facilitate molding and topresent a knife-like edge.

To prevent the nut from turning, the washer must be locked againstrotation. .When the washer is applied to a timber, the flange 1 isstruck a blow adjacent one of the points 6, which will cause said pointto enter the wood as indicated at 6 If the washer is against a metalsurface, instead of bending the point 6, a lug or bur is struck up by apointed tool on the metal surface in the space 6. I

The face of the washer is provided with recesses or grooves whose edgesare adapted to be upset so as to form a lug or projection adjacent theouter edge of the nut to lock said nut against rotation. In thepreferred form of my invention, each recess comprises a beveled portion7, the deepest point of which terminates at a To form the nut lock thepoint of a cold chisel or other suitable tool is placed in the deepestportion of a recess against the shoulder 8, and by striking the oppositeend of the tool the metal will be upset at this point, which upsetportion 8 will prevent the nut from turning.

I consider it an advantage to shape the recesses as herein shown becausethe beveled portion enables the tool to be held at the proper angle inupsetting the metal, and this shape allows the pattern to be drawnfreely from the sand during molding. .I also consider it an advantage tospace the recesses unequal distances apart, or to employ an odd numberof recesses spaced equal distances apart as herein shown, as the cornersof the nut when screwed home will be located at different distances fromtheir adjacent recesses, and the most desirable point may be selectedfor the nut lock. It is a further advantage to employ a plurality ofrecesses because the'locking projection is hammered down to unlock thenut, and if it should break or become fractured another recess could beutilized in forming the nut lock when the washer is used again. However,my invention is not limited to a recess of any particular shape or anydefinite number of recesses.

From the foregoing it will be understood that my invention can beapplied to a malleable iron washer of almost any general construction,and if desired may be used as an ordinary washer without using the nutlocking features.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

1. As a new article of manufacture, a malleable metal washer having araised portion constituting a nut seat, said seat being provided with aradially disposed groove, said groove having one wall substantiallyperpendicular, whereby an upsetting tool may be introduced for thepurpose of upsetting the wall of said groove, forcing the metal thereofin a vertical direction above the plane of the said nut seat;substantially as described.

2. As a new article of manufacture, a malleable metal washer having araised portion constituting a nut seat, said seat being provided with anunequal number of radially disposed grooves, each groove having one wallsubstantially perpendicular, whereby an upsetting tool may be introducedfor the purpose of upsetting the wall of said groove, forcing the metalthereof in a vertical direction above the plane of the said nut seat;substantially as described.

As a new article of manufacture. a malleable metal washer having araised portion constituting a nut seat, and a base flange, said raisedportion being provided with one or more radially disposed taperedgrooves formed with vertical and inclined walls, whereby an rip-settingtool may be introduced for the purpose of rip-setting the vertical wallsof said groove, the up-set metal forming a lock for the nut, the baseflange of said washer having a notch forming points, whereby either orboth of the points may be bent down into a timber to lock the washer inplace; substantially as described.

4 As a new article of manufacture, a malleable metal washer having araised portion constituting a nut seat and a base flange, said baseflange of said washer having a notch within its marginal line formingpoints at the 10 marginal line, whereby either or both of the points maybe bent down into a timber to lock the washer in place; substantially asdescribed.

In testimony whereof I hereunto afiix my signature in the presence oftwo Witnesses, this eighth day of December 1906.
